All of the caching control is now on a per-environment basis. The new
environment.conf file can specify that particular environment's
environment_timeout value. So in order to get this kind of behavior
would either add a new setting for the environment.conf or add a new
valid value for environment_timeout. I'm thinking that adding a "manual"
value to environment.conf would be doable.
# Clear the 'production' environment cache
puppet cache clear
# Clear the 'test' environment cache
puppet cache clear --env='test'
I think those commands would be easily done. You just need to list the
environments, get the configuration for each one and touch the
environment's directory. Right now the don't make the environment's
directory available on that object in the code, AFAIK, but exposing that
should be trivial.
I can imagine that MANUAL control is always there irrespective of the
timeout. This way you can have a long timeout set (say an hour), but you
can also manually touch the directory. This way no additional settings
are required. I don't think there is any harm in always allowing a
manual refresh. However, if changes are made as a checkout/pull of a
complete environment, it may not behave right depending on the order the
files are updated (which depends on the SCM system in use), so I am not
yet convinced that we can simply use the environment's directory itself
as the file to watch.
It was complications like these that made us not implement this in
a way that at first appears to be both simple and obvious (i.e. watch
the environment's directory).
A safe implementation would be to have a second hierarchy of files that
are used solely for cache control. If we have a single control that just
flushes all caches the design is somewhat less ugly...
I so want to see a file called 'tickle_me_elmo" :-)
